About use of the gerund

Two being larger than one is true.
(It is true that 2 > 1.)
I wonder if this sentence is possible.

Well, you made it possible :slight_smile:

It is said that two’s company. That being true, is three a crowd?

The rumour of “two being larger than one” has been proved correct by some mathematicians :slight_smile:

I think that “That being true” is a participial construction.
